Appiimtion ned Mw 3,1907. sanare. 371.724. l

which will cause the gate to automatically swing back to closed positionafter the same is released from open position, and it relates moreparticularly to a hinge of this class that will permit the gate to openand close in either direction. The invention has for one `of its objectsto improve the construction and operation o1" devices of this characterso as to be comparatively easy and inexpensive to manufacture, composedof few parts, of substantial and durable design, and vthoroughlyreliable in use.

A further object of the invention is the provision of a gate hingehaving its post and gate members made of Wrought iron strips bent intothe desired shape and hingedly connected by a pintle bolt, one of themembers having cam arms working on an anti-friction roller and arrangedto cause the gate to automatically close by its own weight.

With these objects in view and others, as will appear as the descriptionproceeds, the invention comprises the various novel features ofconstruction and arrange,- ment of parts which will be more fullydescribed hereinafter and set forth with particular-ity in the claimsappended hereto. i

In the accompanying drawing, which illustrates one of the embodiments ofthe invention, Figure 1 is a side elevation of the hinge shown appliedand holding the gate in closed position. Fig. 2 is a similar viewshowing the gate in open position. Fig. S is a perspective view of themember of the hinge having the cams for causing the gate toautomatically close.

Similar reference characters are employed to designate correspondingparts throughout the several views.

Referring to the drawing, 1 designates a portion of an ordinary gatepost, and 2, the inner vertical bar of a swinging gate that is hingedlyconnected with the post by at least one hinge designated generally by 3,although, if desired, two such hinges may be employed, but for ordinarypurposes, it will be found that a simple form of hinge may be used inconnection with the hinge 3. The hinge 3 is employed for the purpose ol'permitting the gate to close automatically by its own weight and remainin closed position until deliberately opened when it is desired to passthrough the gateway. The hinge 3 comprises a post member 4 and a gatemember 5, both of which may be, and preferably are, constructed of sheetmetal of suitable gage and width. The member 4 has its ends bentlaterally into parallel horizontally extending arms 6 that are aperturedto receive the pintle-bolt 7 extending vertically or parallel with thebody portion of the said member. The post member 4 is secured againstthe post in any suitable manner, as for instance, by screws 8 andarranged midway between the arms 6 and sup- 60 ported on the member 4 isan anti-friction roller 9 jour! naled on a stud l0 riveted to the member4.

The gate member 5 is considerably longer than the member 4 and has oneend bent outwardly and apertured to form a pintle-receiving arm 11disposed above 65 the lower arm G of the member 4, the aperture 12 beingclearly shown in Fig. 3. Adjacent the middle of the member 5, the sameis bent liat against itself, as indicated at 13, and then outwardly intoan arm 14 disposed parallel with the arm 11 and provided with an 70aperture l5 for receiving the pintle-bolt 7. From the extremity of thearm 14 the member' is bent downwardly into a vertically-extendingportion 16 that divides into two branches 17 that are produced bysplitting one end of the strip from which the member 5 is made. 75

These branches 17 are symmetrically curved and extend downwardly betweenthe arms 11 and 14 toward the body portion of the member 5 to whichtheir extremities are secured by rivets 18. Each portion 17 is curvedthrough 1800, the center of curvature being the axis on which the gateturnsnamely, the bolt 7. The bottom edges 19 of the curved element 17constitute cams that engage the roller 9 whereby the weight of the gatewill cause the latter to swing closed from open position on either side.of the member 5 is provided with apertures 20 for receiving screws 2lfor securing the members to the gate, the upper screw-receiving apertureextending through the doubled portion 13 of the member, as shown in Fig.3. cam portion of the member may be reinforced as by a plate 22 securedunder the arm and bearing against the back or plate portion of themember 5. lThis reinforcing plate 22 is riveted to the arm 14 and isprovided with an aperture for receiving the pintle-bolt.

ln practice, the hinge is applied by securing the members 4 and 5respectively, to the gate post and gate in the desired position and thenthe members are secured together by the pintle-bolt 7. Normally theparts are in the position shown in Fig. l, the roller 9 100 beingengaged in the crotch formed by the cam members 17. As the gate is swungopen in either direction, one of the Cams 19 runs upwardly on the roller9, thereby bodily lifting the gate until it is fully opened,

which position is reached when the arm 14 of the mem- 105 to rest by theroller iengaging between the two cam members.

Frein the foregoing description, taken in connection The flat portion orback plate 85 If desired, the upper arm` 14 and 90 with the accompanyingdrawings, the advantages of the construction and of the method ofoperation Will be readily apparent to those skilled in the art to Whichthe invention appertains, and while I have described the principle ofoperation of the invention, together with the apparatus which I nowconsider to be the best embodiment thereof, I desire to have itunderstood that the apparatus shown is merely illustrative and that suchchanges may be made when desired, as are within the scope ot the claims.

Having thus described the invention, what I claim 1. A hinge of theclass described comprising a pair of members having laterally extendingarms. a pintle passing through the arms for hingedly connecting themembers, a pair of inclined cams extending from a point between the armsof one member outwardly toward one of the arms thereof, and a devicesupported on the other member at a point between its arms for engagementwith the cams.

2. A hinge of the class described comprisingl a pintlecarrying member, asecond member having one end bent into an arm to engage the pintle andthe other end divided into downwardly inclined cams, and a roller on theIirst member arranged in cooperative relation with the cams.

A hinge of the class described comprising a member having one endprovided with an apertured arm and bent back upon itself and the otherextremity split and shaped into symmetrically inclined cams with theirextremities secured to the body portion of the member, a pintleextending through the said arm, a second member supporting the pintle,and a roller on the second member engaging the cams.

4. A hinge of the class described comprising a strip of metal having oneend bent laterally to form an arm and an intermediate portion bentlaterally to form a second arm and provided with a divided extremityinclined toward the body portion of the strip and secured to the latterto form cams, a pintle slidable through the arm and between the cams, amember supporting the pintle, and a device on the latter' memberengaging the cams.

5, A hinge of the class described comprising a strip of metal having anapertured arm at one end and doubled back on itself at an intermediatepoint and bent into an arm thereat and having its other extremity splitlongitudinally and the split portions symmetrically curved and in clinedwith their ends secured to the body of the strip intermediate the saidarms, a second strip having its ends bent into arms, a pintle extendingthrough the arms of both strips, and an antifriction roller arranged onthe second strip to engage the inclined and curved portions oi the firststrip, the said portions being curved around the axis of the pintle as acenter'.

In testimony whereof, I aix my signature in presence of two witnesses.
